We study the scalar and spinor perturbation to Kerr-NUT space-time, that is,Klein-Gordan and Dirac equation therein. The equations are invariant underduality transformation between the gravitational electric (M) and magnetic (l)charge, radial and angular coordinate, and radial and angular component of thefield. We solve the equations separating into radial and angular parts.Moreover, if sets of Klein-Gordan and Dirac equation and correspondingsolutions are known for Kerr space-time, under duality transformation, those indual Kerr space-time are shown to be achieved. A few examples of solution areshown. We comment about the horizon and singularity conditions.Comment: 3 latex pages including 1 figure; to appear in the proceedings of X  Marcel Grossmann Meeting, Rio de Janeiro, 20-26 July 2003; on the basis of  talk presente
